The satisfactory performance of a helmet mounted display (HMD) depends very much on satisfying a number of critical criteria relating in particular to the interface between the user and the optical system. The paper describes a test facility that enables these and other optical and electro- optical parameters of an HMD system to be evaluated. A particular feature of the equipment is that it can be used for testing display systems mounted on, or forming an integral part of, the complete helmet. This is made possible by the design of a compact probe that simulates the relevant features of the users eyes and can be placed inside a helmet at the eye positions.
